R Drawing'i To all whom it may concern:

Be it knownthat I, Joserrr A; Scnrrrrms,

. a citizen oftheUnited States, residin at -Knoxville, in the county of Knox and tate of Tennessee, have invented a new and useflll Improvement in Dyeing Compositions, of which the following is a specification.

-My improvement relates particularly to the art-of dyeing silk and cotton and; similar material to any of the light shades which are known as astel 'sha es, such as flesh color, pink, o1 rose, baby blue, sky blue, Alice lue, lavender mauve, green, tan, orange, Nile-green, green, and pearl ra y y The object oft e invention "is to produce a dye in a form and of quality suited-to dyeing such materials of said and similar shades conveniently and b persons who are not skilled in the-art of yeing, to theend that said dye may be used in a domestic way for dyeing such articles as hose, silk gloves,

ribbons, waists, summer dresses, lace ourtains, doilies, and trimmings. 7

"My improved dyein material is in the form. of a concentrate mixture which is to be used as. hereinafter described.

Said mixture is made as follows: Dye-stufi' suitable to the shade which it is desired'to roduce is selected from the coaltar dyesw ich are known under. such names as anilin, alizarin, and benzidin dye-stuff;

To one gallon of water add about eight ounces of-such dye-stuff and about one. quart of anilin oil or mono ole oil, or any other similar coal tar oil solu le in water and about two ounces of common salt (sodium chlorid). If it is desired'to produce soft color I tones also add about half an ounce of chalk (calc um. carbonate). The chalk is preferably added in all cases; for its presence is not objectionable, even if it is not desired to produce soft color tones. Thoroughly dissolve. or intermingle th several indients in the water by agitation and by gre such heatin "as maybe necessa The water'is pre erably boiling when t e other ingredients aread e '1 a n this manner the commercial product is repared. Thisiliquid is then 'put into and opt in suitable receptacles until mentioned. For these eof economy, iti's light green, medium rtions j are'to 'be used for dyeln the materia s above Specification of Letters 1mm. P t te 20, 191

preferable to makethe mixture as strong as the ingredients will permit; but all of the soluble ingredients should be dissolved as fully as may be and so remain, in'order that whenever any portion of the material is taken from the receptacle, said portion will be in liquid form and fully adapted to rack ing a dilution which will be even throu b out. The receptacles are preferably g ass bottles. holding one or two ounces of "the concentrated mixture. v

For dyeing any of the fabrics above mentioned, take water, in a clean vessel, in ample quantity to permit immersing the fabrics and moving them about while so immersed. To this water add, drop-bydropffrom the concentrated dye-stuff until the liquor formedby said water-and these small quantitles of concentrated dye-stuff illiXtlll'e is of the desired strength. If it dyeing liquor, the shade becoming darker with the prolongation of the immersion of the material. I It is advisable not to use too much of the concentrated mixture, preference being given to prolonging the periodof immersion. p

The concentrated dye-stuff mixture is complete in'itself, excepting that it does not contain enough. water for dyeing the fabrics.

Hence nosalts or acids are to be added by the person who is to d e the fabrics. Merely water is to be added or the purpose of very much reducing the concentrated mixture. For the purpose of making the concentrated mixture uniform, the bottle is ,taibe well shaken before taking a' portion therefrom for 'makin the diluted dyeing liquor.

The fabrics to be dyed must be clean and they are preferably made wet with water before they" arev immersed in the diluted dyeing 'li uor. Leave liquor until-the desired shade has been obtamed. Then rinse in one. .or more clean' the fabric in the a water baths. Wring or squeeze out well and hang in a shady place for dry' being made as smooth as possi I claim as my invention,

1. In the art of dyeing, scribed dye comprisin coal tar d e-stufl', common salt, and 00:1 tar oil so uble in water, substantially as described.

the hereinde- 2. In the artof dyeing, the herein-described dye comprisin common salt, and coa tar oil so uble in water and chalk, substantially as described.

In testimony whereof I have signed my name this 22nd day of August, in the year one thousand nine hundred and sixteen.
